摘要：

The coefficient of ellipticity of the liquid-vapor interface of liquid argon has been measured to be »×104=5.70.4 at 90°K, rising to 8.80.6 at 120°K. Assuming a Fermi density profile and isotropy of the dielectric constant in the interface region, this yields a 10%-90% interface thickness t(90°K)=7.90.5 and t(120°K)=15.21.0, averaged over a surface dimension of the wavelength of light. The measurement is compared with predictions, and theoretical uncertainties are emphasised. © 1979 The American Physical Society.
